Load the given URL and make the text size bigger a few times. I'm working on this. So far I've discovered that the crash (for me) is caused by textrun construction building a textrun with missing characters. In particular there's some text ". Box Office Mojo. Retrieved on 2007-04-09." for which we build a textrun which is actually ". Box Office Mojo. Retrieved on -04-09." --- i.e. the "2007" (which has its own DOM element and frame) is skipped. This causes problems because gfxTextRun::MeasureText returns zero for that substring and the text frame ends up thinking none of its text fit, and gets confused because non-whitespace text at the start of a line not impacted by a float should always have some text forced to fit.

After the check-in of bug 385270, it seems to hang instead of crashing.
This works for me on Mac. Can you still reproduce? Can you get a stack trace for the hang?
Well, I can't repro the hang anymore with 2007082805.
FWIW, this works for me too with a 2 days old build on Windows.
I think this is fixed now.
